The heat pump is a machine that draws heat from one place to another investment of external work. Usually it is from the colder to warmer place. Heating heat pump is a device that uses non-traditional sources of energy for central heating and hot water. The basic view of heat pumps is that the planet''s global temperature regime is directly added heat from the combustion of any fuel. Indirectly, there is a certain amount of heat in power plants - the production of electricity consumed for heat pump operation. In the first part of my project I explain the heat pump principles. Then are described the heat sources for heat pumps, divide the heat pumps depending on driving mechanisms, heat sources and using energy. This part also described the heat pumps like water to water type, earth to water type, air to water type, the basic parts of the heat pump like compressor and convertible of heat. Second part describes using the heat pumps like onditioning, heat pump like alternative source in household and different systems. The third part contains calculations of heat decreases and heat pump design. Finally are compared different types of heating with heat pump.
